The Royal Albert Hall is in a particularly regal mood tonight, as Clive Myrie, with special guests, presents a Prom of music written for royal occasions in honour of Her Majesty the Queen's platinum jubilee.Conductor Barry Wordsworth leads the BBC Concert Orchestra and BBC Singers in a varied programme featuring works by the very best British composers from across the last 500 years. Expect triumphant trumpet fanfares, soaring choruses and glorious organ playing, with particular highlights to include Handel's ever-popular coronation anthem Zadok the Priest, Parry's I Was Glad - which ushered the Duchess of Cambridge down the aisle - and even a song written by Henry VIII.
